The permissions are now checked also when trying to the title of the
plugin.

This fixes a problem on PHP 7.2. However ultimately this class should be
dropped in favor of the native json_decode/json_encode functions.

Remote API calls should have some unittest as this test would have caught
the bug that was introduced in 96d46bf4
and fixed in ebf17449

Our test suite did not reset the config directory for each test class as
it does for the data directory. In addition it copied all files from the
main config directory over. Both may create an unpredictable state for
tests.

This streamlines the initialization.

Looks like the domain we used to test this on expired.

Specifically, this pull request checks if the current query is already a
valid pageid and then return that as suggested pageid.

Also, tests are added for this method.

Fixes #2355

PS: We may want to somehow better educate/nudge users to use the better
way of creating pages by creating links on existing pages.

Before this change, HTML and some JS code (as far as it was not escaped
by json_encode) could be injected into the output as the closing pattern
that is checked by the regex is not escaped in JSON (see test case).

Quotes are now optional, the options are spearated by space

While it's generally frowned upon testing privates, it can often be
useful and the easier way to write tests. Eg you want to test something
complicated method that is important, but you do not want to expose it
directly to other classes...

This new method uses reflection to make access to such methods possible
from within tests without the need for intermediate classes.

As discussed in #1933

To allow creating links with manipulated versions of the current search
query an unparser is necessary. However, the current output of ft_queryParser
makes some advanced features hard to detect. Therefore the new
ft_queryUnparser_simple cannot handle negated phrases and `OR` searches.

It should still cover 98% of search queries.

The data for the section edit button is now passed as an assoziative array which is
encoded in the '#<!-- EDIT(.*) -->#' placeholder as an JSON array.

There was a bug, where the options array ['Auto', 0, 1] would result in
HTML option tags where both the 'Auto' and the 0 option were selected.

closes #2129

No globals required anymore, somewhat more general approach to sending
data to the test system. Clean access through keys.

reformatting
fixing of doc blocks
making internal vars protected

Test code for workflow 'show - sectionedit - save/cancel' (with modifications in test classes and 'send_redirect()' and 'act_dispatch()'.

hopefully this will help with figuring out why our HTTP tests sometimes
fail on travis.

just to be sure, we're not breaking something simple here.

added test coverage
